According to The Hollywood Reporter, screenwriter Laeta Kalogridis, who worked with director James Cameron on the script for his Oscar-winning blockbuster Avatar--she was officially credited as "Executive Producer"--has been hired for rewrites on the Fox remake of the 1966 sci-fi flick Fantastic Voyage, which Cameron will produce with his Lightstorm Entertainment partner Jon Landau.

The original movie involved scientists who are shrunk down and injected into the body of a sick patient in order to cure them, and "Bourne" director Paul Greengrass had originally been slated to direct the 3D project, which has been in development for many years with earlier screenplays written by Shane Salerno (Armageddon) and Cormac and Marianne Wibberly (National Treasure).

The story also reports that Kalogridis is still working on a script for a live action remake of the Japanese anime Ghost in the Shell for DreamWorks, and on Nine Lives for Jerry Bruckheimer and Disney. ComingSoon.net previously spoke to Kalogridis about the former, while the writer was doing press for Martin Scorsese's thriller Shutter Island earlier this year.

Shawn Levy will direct Fantastic Voyage for 20th Century Fox and producer James Cameron, reports Deadline.

Set to use the same 3D technology Cameron used for Avatar, Fantastic Voyage is about a scientist who is dying of a blood clot. His only chance for survival is for five scientist colleagues to be miniaturized in a ship, and injected into his bloodstream.

The film is a remake of the 1966 original directed by Richard Fleischer and starring Raquel Welch and Donald Pleasence.

Shane Salerno wrote the script, which is being polished by Laeta Kalogridis.

Levy's credits include the "Night at the Museum" films, Date Night and the upcoming Real Steel with Hugh Jackman.

David Goyer (Batman Begins, Man of Steel) is the latest writer said to be taking on the long-gestating Fantastic Voyage at 20th Century Fox.

Set to be produced by James Cameron and to make use of the same 3D technology he used for Avatar, Fantastic Voyage is about a scientist who is dying of a blood clot. His only chance for survival is for five scientist colleagues to be miniaturized in a ship, and injected into his bloodstream.

The film is a remake of the 1966 original, directed by Richard Fleischer and starring Raquel Welch and Donald Pleasence.

The project has come close to moving forward a few times, most recently three years ago when Shawn Levy was nearly set to direct and rumored headliners included Will Smith and Hugh Jackman.

"'Fantastic Voyage' I've been working on with Jim Cameron for the last seven months," Levy told us in 2011. "We've got a script and a world design that we love. It'll be an underwater, 3D action sci-fi extravaganza."
